What are Stainless Steel Filler Wires?

Stainless steel filler wires are a type of welding wire used in arc welding processes such as TIG (Tungsten Inert Gas) or MIG (Metal Inert Gas). They come in different alloys, but ER308L is the most commonly used alloy for stainless steel because it has excellent corrosion resistance. The “ER” stands for electrode rod, and the “L” stands for low carbon content. The low carbon content makes this alloy an ideal choice for welding stainless steels with higher levels of chromium and nickel, such as 304 or 316-grade steels.

When welders use Stainless Steel ER308L Filler Wires for TIG or MIG welding processes, the flux on the surface of the wire melts and releases gases that help shield the weld from contamination. It also ensures a strong joint between two pieces of metal with minimal distortion from heat input. The shielded arc also provides stable amperage throughout the process, ensuring smooth beads and precise control over your welds.

Benefits of Stainless Steel ER308L Filler Wires

Corrosion Resistance Properties

The most significant benefit of using stainless steel ER308L filler wires is their strong corrosion resistance properties. Make them ideal for welding and fabrication projects that will likely come into contact with harsh chemicals or corrosive environments. With these types of applications, ensuring that the weld is not compromised by corrosion over time is essential. Thanks to its high resistance, stainless steel ER308L filler wires can provide peace of mind regarding the longevity and reliability of your project.

Durability and Strength

Another great benefit to using SS ER308L filler wires is their durability and strength. These filler wires have a high tensile strength, making them perfect for applications where strength and flexibility are important factors. Additionally, thanks to their low carbon content, they can be welded without any risk of cracking or warping during cooling after being heated.
